Table 2.

True negative rate (TNR) achieved by our model when its false-negative rate (FNR) are 0.01, 0.02, 0.03 and 0.05 as we vary prediction threshold for assigning observations to a positive class indicating malignancy. The 95% confidence interval of the estimated TNR and the clinical meaning are also provided

clinical meaning	FNR	TNR	95% CI of TNR
